TRUNNANO’s diverse portfolio of sodium-ion layered oxide cathodes spans the primary crystal structures critical to advanced sodium-ion cells. These include the O3-type, P2-type, P2/O3 biphasic, single-crystal, and high-entropy configurations. The company has meticulously organized these innovative materials into six distinct product series, each designed to meet specific industrial demands and performance benchmarks.
Addressing Core Challenges in Cathode Development
Sodium-ion cells present a compelling alternative to lithium-ion technology, primarily due to the abundance and lower cost of sodium. This makes them particularly attractive for large-scale stationary storage applications and other cost-sensitive sectors, including certain electric vehicle segments.
Layered oxides, in particular, are favored as a main cathode material for sodium-ion batteries because of their relatively high specific capacity and their compatibility with existing lithium-ion manufacturing processes. This compatibility can significantly ease the transition and adoption of new battery technologies.
However, the development of layered oxide cathodes has faced persistent challenges. These include limitations in structural stability, the complexity of phase transitions during charge and discharge cycling, and a notable sensitivity to air, which can impact material integrity and battery longevity.
TRUNNANO asserts that its proprietary solutions directly address these long-standing issues. The company employs a multi-pronged strategy encompassing elemental doping, intricate biphasic structure design, advanced surface modification techniques, and pioneering high-entropy strategies. These methods are crucial for enhancing the durability, cycling stability, and overall safety of their sodium-ion layered oxide cathodes.

The performance characteristics of TRUNNANO’s new materials demonstrate significant advancements. A high-nickel single-crystal grade, for instance, achieves an impressive discharge capacity of 168 mAh/g. This particular attribute positions it ideally for power-battery applications, where high energy density and rapid power delivery are paramount.
Furthermore, the company’s high-entropy and biphasic grades are engineered for enhanced longevity and thermal stability. TRUNNANO reports that these materials exceed 2,000 cycles, a critical benchmark for applications requiring extended operational lifespans and robust safety features. The improved thermal stability is vital for preventing thermal runaway and ensuring reliable performance under various operating conditions.
In another notable development, TRUNNANO’s lithium-doped and lithium-rich grades push the boundaries of specific capacity. These materials can reach a specific capacity of 200–210 mAh/g by activating oxygen redox mechanisms. This innovation signifies a pathway to achieving higher energy densities, making these materials suitable for applications demanding maximum energy storage within constrained volumes.
